Figure 4-12 AGC Config Window

Maximum Gain specifies how much gain the AGC can apply in its attempt to bring the output signal up

to the proper level. The greater the Maximum Gain, the lower the output signal level that can be

brought up to proper level. The Maximum Gain options are 5dB, 10dB, 15dB, 20dB, 25dB, 30dB, and

35dB. For most near party/far pary applications, the 10dB setting is recommended. Maximum Gain

settings greater than 10dB may elevate background noise during pauses in speech. A “soft AGC” using

5dB is often useful even when large voice level differences are not present.

The Link option is provided in Stereo Input Mode settings to give the user the option of making the

AGC gains on the two output channels Linked or Independent (In Mono Input Mode, the linking

option is irrelevant). When Linked, the AGC gains are equal at all times, and are increased in response

to the largest signal level of the two output channels. When Independent, the AGC gains are not

necessarily equal, each increased in response to only its own output channel. For most applications, the

AGC outputs should be Linked to avoid annoying Left/Right differential gain shifts and loss of stereo

perspective; however, Independent AGC gains should be used when processing two unrelated

monophonic signals in a Stereo Input Mode.
